Comet C 2019 Y4 was discovered on December 28th 2019 by Asteroid Terrestrial-Impact Last Alert System (ATLAS) search program. At the time of discovery the comet was from 19.6 mag. This image shows the comet on April 13th 2020. It is obtained by combining the RGB data from IRIDA-North 12" Astrograph and luminance data from 12" RC with Astro-Physics corrector @ f/5. In the picture, you can see several fragments of the comet nuclei. With that, the chance of this comet reaching high brightness sharply decreases.
